PRESSURE LUBRICATOR.

Application filed November 5, 1926.

The main object of this invention is to provide a device particularly adapted for the lubrication of vertical rails in an elevator shaft, and is mounted on the elevator car, comprising a container equipped with a pressure pump which forces a constantly flowing column of oil to a series of nozzles 'from which the oil is ejected directly onto the rails.

Another object is to provide a pressure lubricator equipped with ejector nozzles which squirt several streams of oil upon rails in an elevator shaft and which oil is then distributed by spreaders which are part of the device and may be adjusted to an active or inactive position.

The above and other objects will become apparent in the description below, in which characters of reference refer to lil e-named parts in the drawing.

Referring briefly to the drawing, Figure 1 is a side elevational view of the pressure lubricator with the spreader wings omitted for the sake of clarity.

Figure 2 is a top plan view of Figure 1.

Figure 3 is a. sectional elevational view taken on line 33 of Figure 2, showing the means for locking the spreader device in active and inactive position.

Referring in detail to the drawing, the numeral indicates a cylindrical container. The latter has a semi-spherical roof 11 provided with an opening which is closed by afiller cap 12. The shell 13 of a pump communicates with the chamber in the container and extends angularly from the roof. The piston of the pump slidable in the shell 13 is actuated by manipulating manually a handle 15 attached to the stem 14 which is in turn secured to the piston (not shown). The roof 11 of the container is recessed at one position to form a ledge on the container on which is mounted a vertical pipe 16 which is surrounded by an elbow 17. An additional upright elbow 18 is'connected by a pipe 19 to the first-named'elbow and provides a means of communication to a nipple 2O surmounted by a T-joint 21. Three openings are formed in the latter, two aligned, and one extendingat right angles to the aligned openings. The aligned openings of the T-joint havev one of the ends of semi-circularly curved tubes inserted in them. These tubes indicated by the numerals 22 and 23 are provided with tapering ends 2 1 Whose openings face each other and Serial No. 146,429.

provide nozzles adapted to lubricate opposmg surfaces 25 of the arm of the T-guide rail commonly used in elevator construction. A third nozzle 26 is inserted and secured in the remaining opening of the T-fiXture and the stream therefrom lubricates the back of the guide rail.

The semi-circularly curved tubes each are provided with a sleeve 27 which is rotatable on the tube and has an arm 28 extending therefrom in a normally angular position. The lower end of a spreader wing 29, curved at its upper end is secured to the arm by rivets or similar means. Each arm is provided with a pin 29 which projects from the side and is engaged in one of a pair of slots formed at each end of an adjustment bar 31 which spans the distance between the arms and retains the curved surfaces of the wings in contact with the side surfaces 25 of the elevator rail.

In use, the container 10 is filled with oil and the ring 32 having the notches 33 is mounted on the elevator car which is guided between rails which are to be lubricated. hen the lubricating device is in proper position on the car the arm of the rail having the surfaces 25 thereon will be positioned between and in contact with the curved surfaces of the spreader wings 29 which distribute the oil over the entire surfaces 25 of the guide rail as the streamsof oil are ejected from the nozzles 24 and 26. The oil is emitted from the device for any length of time desired by manipulation of the stem 14 by grasping the handle 15 which causes air to enter the can to urge the oil therein to circulate thru the pipes 16, 19, and 20, and thence into the nozzles 24 from which it passes in thin circular jets.

It is to be noted that certain changes in form and construction may be made without departing from the spirit'and scope of the invention.

I claim 1. In a pressure lubricator, a container, a pump communicating with said container, tubes extending from said container and having nozzles facing each other, spreader wings pivotally mounted on said tubes, and means connecting said wings for securing said wings in two positions.

2. In a pressure lubricator, a container equipped with a communicating pump, a pipe line projecting from said pump, a pair of semicirculafly curved tubes extendin horizontally from said pipe line, the outlets of said tubes facing each other, rotatable Wings mounted on said tubes, and a bar releasably connecting said Wings.

3. In a pressure lubricator, .a container equipped With a communicating pump, a pipe line projecting from said pump, a pair of semi-circularly curved tubes extending horizontally from said pipe line, the outlets of said tubes facing each other, rotatable Wings mounted on said tubes, a barreleasably connecting said Wings, saidbar having a pair ofslots' near each end, and means-on said Wings registering in said slots for adjustably ecuring sa d Wings in various positions.

gt. In a pressure lubricator, .a container equipped With a communicating pump, a pipe line projecting from said pump, a pair of semi-circularly curved tubes extending horizontally from said pipe line, the outlets of said tubes facing each other, rotatable wings mounted on said tubes, a bar releasably connecting said Wings, said bar having apair of slots near each end, means on said Wings registering in said slots for adj ustably securing said Wings in various positions comprising sleeves secured rotatably on said tubes, arrns extending from said sleeves, pins on said arms engaging in the slots of said bar for positioning said Wings.

In testimony whereof I aiiix my signature.
